SiLSI4461-C2A-GM
Overview
The SI4461-C2A-GM is a high-performance, low-current sub-GHz RF transceiver covering the 142 MHz to 1.05 GHz frequency range. It offers exceptional sensitivity of -129 dBm and output power up to +16 dBm, making it ideal for long-range wireless links while maintaining low power consumption.
Why Choose This Part
The transceiver provides a significant link budget via its high sensitivity and +16 dBm power output, supporting data rates up to 1 Mbps. Its low active current of 10-13 mA in receive and 43 mA in transmit at full power enables multi-year operation on small batteries.
